1731 (poplevel): Delete #if 0 block. Make externals invisible
1732 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1733 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1734 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1735 (duplicate-decls): For real parm decl after a forward decl,
1736 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1740 local-over-local. Clarify comments.
